트라이엠시놀론아세토나이드

개요Triamcinolone acetonide is a synthetic corticosteroid. It decreases cytokine levels, the firing rate of sensory neurons, and mechanical hypersensitivity in a rat spinal nerve ligation model when used at a dose of 1.5 mg/kg prior to and following surgery for three days. Triamcinolone acetonide also decreases outflow facility in a mouse model of steroid-induced glaucoma when 20 μl of a 40 mg/ml suspension is administered subconjunctivally. Formulations containing triamcinolone acetonide are used in the treatment of diabetic macular edema.

일반 설명The three main metabolitesof triamcinolone acetonide (Azmacort, Nasacort) are 6β-hydroxytriamcinolone acetonide, 21-carboxytriamcinoloneacetonide, and 6β-hydroxy-21-carboxytriamcinolone acetonide.All are much less active than the parent compound.The 6β-hydroxyl group and the 21-carboxy group are bothstructural features that greatly reduce GC action. The increasedwater solubility of these metabolites also facilitatesmore rapid excretion.
